What do we do?

Hi, we're Segment, and we're building the future of analytics infrastructure: the single place to collect and organize your customer data.

Every big company ends up spending a ton of time building their own in-house plumbing for handling stuff like pageviews, event tracking, and user behavior. But really, they shouldn't have to. So we built a routing in the middle to handle it all. Our customers send data to us, and then we fan it out to a myriad of different analytics services–everything from Amplitude to Zendesk.

Technical challenges

1) We're currently processing on the order of billions of events and terabytes of data per day. This is up significantly more than 10x from last year. This leads to a lot of pretty interesting problems which we're just seeing for the first time at our new order of magnitude of scale!

2) We are active in the open source community - here are a few of our awesome repos: http://analytics.js,nightmare.

3) We have about 150 integrations with external partners. This has proven an interesting architectural problem - it's certainly very challenging to ensure that things never break in the face of changing partner APIs!

Why join us?

- We're heavily committed to open source (there's a little over 400 repos on Github).
- We're handling billions of API calls a month.
- We're adopting some cutting edge technology e.g. Docker and Terraform.
